I did an update on installed PSoC Creator from version 4.01 Update 1, to Version 4.1. After this, I tried to re-compile a project by using the new version. Of course, first I had updated the project components (Project -> Update Components). Unfortunately teh project does not compiled without errors, while in the previous PSoC Creator version the compilation was OK.

I received the following error messages:

1. E2713: <sensors(2)> cannot be placed at <P2[2]> because the location does not support the required features: <ROUTABLE>. The placer reported an error.

The error indicates an issue with the fitter which takes care of analog/digital routing.

Make two copies of the project. Open one of them using 4.0, and the other using 4.1. Check if pin allocations are same in the two projects. Maybe pin allocations got messed up during the update process.

Yeap, it looks like a bug. Exactly the same project was fitted OK by using the previous PSoC Creator version. The only action i did is to update the components (Project -> Update Components). The P2[2] is a digital input, connected on a switch. Also an edge interrupt is assigned at the P2[2].
